A TS7500 solution is a valid configuration of TS7510, TS7520, or TS7530 hardware, in combination
with a version of TS7500 software. Intermix between TS7510 and TS7520 components is not supported.
TS7530 hardware may be intermixed with TS7520 disk cache. TS7500 V3.1 software will not function
with TS7510 Virtualization Engine Model CV5 servers. Existing implementations with TS7500
Enterprise Edition V2.1 software and TS7520 hardware components are able to upgrade to TS7500
Enterprise Edition V3.1 software. Refer to the
Description
section for details.

The IBM Virtualization Engine TS7500 solution is a virtual-tape solution designed to help improve
tape processing. Through the implementation of an integrated, tiered storage hierarchy of disk and
tape, the benefits of both technologies can be leveraged to help enhance performance and provide the
capacity needed for today's tape processing requirements. Deploying this innovative offering can
help reduce batch processing time and management overhead.

All prior functions supported by Enterprise Addition V2.1 are also supported in V3.1, with exception
of support for execution of functions on IBM TS7510 hardware components.

TS7500 Supported functions

The following functions are supported in the Virtualization Engine TS7500 solution with IBM
Virtualization Engine TS7500 Enterprise Edition V3.1 software.

Network replication: Copies a complete virtual volume from one TS7500 Virtualization Engine to
another across an IP network. At prescribed intervals, when the tape is not in use, changed data
from the primary virtual tape is transmitted to the replica resource on the target Model CV7
Virtualization Engine so that they are synchronized. The target Model CV7 Virtualization Engine is
usually located at a remote location. Under normal operation, backup clients do not have access to
the replica resource on the target server. If a disaster occurs and the replica is needed, the
administrator can promote the replica to become the primary virtual tape so that clients can access
it.

Network compression: Uses software compression on data that is transferred across an IP network
during a network replication. Network Compression improves overall bandwidth between two TS7500
Virtualization Engines that are replicating virtual volumes, because the data will be compressed
before being sent over the IP network.

Network encryption: Secures data transmission over the network during replication. Initial key
distribution is accomplished using the authenticated Diffie-Hellman exchange protocol. Subsequent
session keys are derived from the master shared secret, making it very secure.

Failover and failback: Failover supports high availability for TS7500 solution operations, and can
help eliminate the down time that can occur, should a TS7500 Virtualization Engine fail. In the
TS7500 solution failover design, a TS7500 Virtualization Engine is configured to monitor another
TS7500 Virtualization Engine. In the event that the Virtualization Engine being monitored fails to
fulfill its responsibilities to the SAN clients it is serving, the monitoring TS7500 Virtualization
Engine will take over its identity. When this happens, the worldwide node names and IP addresses
associated with the failed TS7500 Virtualization Engine are transferred to the surviving TS7500
Virtualization Engine. The failback occurs when the system has recovered.

Secure tape: Implements the Advanced Encryption Standard (AES) algorithm published by the National
Institute of Standards and Technology, an agency of the U.S. government. With this option, you can
create one or more keys that can be used to encrypt the data when it is exported to physical tape
and decrypt when it is imported back to virtual tapes. Encryption helps make the data on the tape
unreadable, unless the appropriate key is used.

Local replication: Copies a complete virtual volume in the same TS7500 Virtualization Engine. Local
replication is the same as network replication, except the target and source servers are the same.

NDMP backup: Enables backup applications and NAS devices to perform backup and restore using the
Network Data Management Protocol (NDMP) V4 protocol over an IP network. The TS7500 solution acts as
an NDMP server, centralizing management while reducing or eliminating locally attached tape devices
from each NAS device. When a backup occurs, data is moved from a NAS device directly to the virtual
library.

Note:
NDMP backup is mutually exclusive with Failover/Failback.

iSCSI: Enables SCSI commands to be used over an IP network and hosts to connect via Ethernet instead
of Fibre Channel.

Hosted backup: Makes virtual tape libraries and drives available to local systems by allowing backup
applications to be installed directly onto the TS7500 Virtualization Engine, reducing or eliminating
the need for a dedicated backup server.

Note:
Hosted Backup is mutually exclusive with Failover/Failback.

Control path failover and data path failover: Enables automatic control path failover to a
pre-configured redundant path without aborting the current job in progress. It also provides
failover for multiple redundant paths in a SAN environment by automatically providing error recovery
to retry the current operation using alternate, preconfigured paths without aborting the current job
in progress. This can provide flexibility in SAN configuration, availability, and management.

Console and capacity support: Management console and capacity support is offered on a tiered, per
TB basis for clients ordering the Enterprise Edition. It includes the IBM Virtualization Engine
TS7500 Management Console program, as well as entitlement to use the available disk capacity.

The quantity of management console and capacity support required for every TS7520 Cache Controller
and TS7520 Cache Module allocated to the TS7530 Virtualization Engine is dependent on the capacity
feature selected on each cache unit.

Virtual tape library functions

The TS7500 solution can assist with infrastructure simplification by enabling multiple disparate
backup servers and applications to share the same physical resources. This can help reduce the need
for multiple tape libraries and improve the overall utilization of the tape storage systems. The
TS7500 can present up to 512 distinct virtual library images.

The following devices can be emulated in the TS7500 virtual tape library, supported by the TS7520
Cache Controller and Cache Module:

Accessibility by people with disabilities

Section 508 of the U.S. Rehabilitation Act

IBM Virtualization Engine TS7500 Software V3.1 is capable as of June 13, 2008, when used in
accordance with IBM's associated documentation, of satisfying the applicable requirements of Section
508 of the Rehabilitation Act, provided that any assistive technology used with the product properly
interoperates with it. A U.S. Section 508 Voluntary Product Accessibility Template (VPAT) can be

The IBM Virtualization Engine TS7500 solution is designed to be a
high-performance, high-capacity open systems virtual tape solution that
can augment the tape backup and restore process in large tape
environments. The TS7500 solution can aid in the tape backup and restore
process by helping to give significant operational and throughput
efficiencies via tape virtualization, namely:

Backup window reduction

Hardware-based compression

Restore time reduction

Data sharing and ease of resource virtualization

High availability options

Integrated server, disk, and tape solution for IT Optimization

The TS7500 solution is a tape virtualization solution for open systems
attachment over Fibre Channel or iSCSI interfaces. It can help support
significant operational efficiencies by storing recent data in the TS7500
solution disk cache. As data ages, the older data may be migrated to
real tape for longer term storage. Since data is now written to virtual
tape via the disk cache, heavy daily tape drive usage can be greatly
reduced.

A TS7500 solution equipped with one TS7530 Server has up to 12 Fibre
Channel ports available for host or tape attachment and up to 10 Ethernet
ports for iSCSI host attachments, depending on the server configuration.
A TS7500 solution equipped with two TS7530 Servers has up to 24 Fibre
Channel ports available for host or tape attachment, and up to 20
Ethernet ports for iSCSI host attachments.

The TS7500 solution differs from many other open systems virtual tape
offerings, by enabling either direct tape attachment or parallel tape
attachment. With direct tape attachment, real tape drives or libraries
are physically attached to the TS7500 solution. With parallel tape
attachment, real tape drives or libraries are attached to the host server
and data is transferred from the TS7500 solution through the host server
to real tape drives or libraries that are physically attached to the host
server.

The TS7500 solution can help reduce the backup window in many
installations. Since robotic movement, tape load/thread, and physical
tape search and rewind are greatly reduced in virtual tape, the effective
utilization of the Fibre Channel interfaces is high. That means more
tape jobs can be run to virtual tape over a single interface than to real
tape. If the backup window is reduced, the time allowed for migration to
real tape is increased, thus potentially reducing the number of real tape
drives needed for longer-term backup data storage.
